Report: TR 2004/23
Author: Michael Duffy
Waikato Regional Council has established a comprehensive Waikato River catchment based funding policy to address soil conservation, river management and flood protection issues across the entire Waikato catchment area.
Consultation with landowners has identified issues in specific catchments, which require attention. The Mangatutu River Management Group was formed as a result of this consultation and its main aim is to address river management issues in the Mangatutu River.
Riverbank erosion and gravel management are the main issues in the catchment that have been raised by the River Management Group. Waikato Regional Council will focus on the river works and address those soil conservation works on individual properties on a case by case basis.
The Mangatutu River has historically been excavated by individual landowners. Through this process the river has degraded in places, while in other places along the river it is shallow and has severe bank erosion.
An integrated river and catchment management plan is considered the appropriate way to provide consistent information and advice to deal with stabilising the river through erosion control works, gravel placement and riparian plantings.
